Description

CROSS-REFERENCE TO RELATED APPLICATION

This patent application claims the benefit and priority of Chinese Patent Application No. 202410568584.6 filed with the China National Intellectual Property Administration on May 9, 2024, the disclosure of which is incorporated by reference herein in its entirety as part of the present application.

TECHNICAL FIELD

The present disclosure relates to a white cane capable of emitting light throughout its body, and belongs to the technical field of auxiliary tools for helping blind people to walk.

BACKGROUND

Blindness and visual impairment are serious social and public health problems in the world, and there are a large number of visually impaired people in the world. At present, there are nearly 45 million blind people in the world and 135 million people with visual impairment. China is one of the countries with the largest number of blind people in the world, with 6-7 million blind people, accounting for 18% of the total number of blind people in the world. In addition, there are 12 million patients with binocular low vision.

The information obtained by normal people through vision accounts for 70%-80% of total information, and the dark world largely limits blind people's access to information. At present, the main tools to assist blind people when traveling out daily are guide dogs and white canes. The guide dog is high in training cost, needs daily consumption, has a limited life span, and is free of the possibility of widespread promotion. The white cane can help blind people sense the environment when traveling out to complete tasks such as detecting obstacles and assisting in going up and down stairs.

However, most of the existing white canes only focus on the purpose of sensing the environment, and do not consider catching attention from others to ask for help or warning others to avoid. Aiming at this problem, the Chinese patent 201220737864.8 designs a white cane with a roller capable of emitting light to remind others of avoiding the blind people. However, the white cane has a disadvantage that the white cane is not obvious since light is emitted at the handle or the roller, and also cannot play a role in the scene of asking others for help.

Therefore, it is necessary to invent a novel white cane capable of emitting light throughout the body so as to solve the above-mentioned problem.

SUMMARY

An objective of present disclosure is to provide a white cane capable of emitting light throughout its body. The white cane can remind pedestrians and drivers to actively avoid during day and night through a cane body capable of emitting light.

Referring to FIG. 1 and FIG. 2, a white cane capable of emitting light throughout its body in an embodiment of the present disclosure is provided. The white cane provides convenience for blind people when traveling out. The white cane can remind pedestrians and drivers to actively avoid during day and night through a cane body capable of emitting light, and can feed back a current light-emitting state to a blind user through the loudspeaker and play specific audios for others to ask for help, so that the traveling safety of blind people is greatly improved. The structure includes a white cane main body, a warning assembly, a control module 5 and a battery 53.

The white cane main body includes a handle 1, a cane body 2 and a cane tip 3 connected in sequence, and a wrist strap 6 arranged on the handle 1 and fixedly connected with the handle 1. The cane body 2 is made of transparent materials. The cane body 2 and the handle 1 are hollow structures. The cane body 2 is detachably connected with the handle 1 and the cane body 3, respectively. Different lengths of cane bodies 2 can be selected according to height of the blind user, and different styles of cane tips 3 can also be replaced according to road conditions. Meanwhile, after the cane tip 3 is worn out due to long-term use of the white cane, a new cane tip 3 is replaced without changing the whole white cane, so that service life of the white cane is prolonged, and using cost is reduced. The wrist strap 6 can sleeve the wrist of the blind user to prevent the white cane from falling off from the hand.

The warning assembly includes a light-emitting light strip 4 arranged on the cane body 2 and a loudspeaker 7 arranged on handle 1. Specifically, the light-emitting light strip 4 is installed and placed in the cane body 2, the light-emitting light strip 4 includes a plurality of LED lamp beads, and emitting colors of the LED lamp beads include red, green and blue. The LED lamp beads can emit light in corresponding proportions, and various colors of light is formed after the colors are mixed. As mentioned above, the cane body 2 is made of transparent materials. The cane body 2 is fitted with the light-emitting light strip 4. The whole cane body 2 can emit various colors of light, and applicability is balanced during day and night, so that the warning effect is obvious, and blind people can travel out all the day comfortably. Light-emitting modes of the light-emitting light strip 4 include a normally on mode and a flicker mode according to set patterns.

The loudspeaker 7 is placed in the handle 1, upper sound holes 11 are formed in a top wall of the handle 1, side sound holes 12 are formed in a side wall of the handle 1, and the loudspeaker 7 can play various audios such as a plurality of cue tones related to working condition of the white cane and a warning sound specifically designed for blind people.

The control module 5 includes a main control chip 52 arranged in the handle 1, and a plurality of control buttons 51 arranged on the handle 1 and electrically connected with the main control chip 52. The light-emitting light strip 4 and the loudspeaker 7 are electrically connected with the control chip, respectively. Light-emitting status of the light-emitting light strip 4 and playing status of the loudspeaker 7 are controlled through the control module 5. The blind user changes the light-emitting mode of the light-emitting light strip 4 through pressing the control button 51 corresponding to the light-emitting light strip 4. When the light-emitting status of the light-emitting light strip 4 is changed, the loudspeaker 7 can emit corresponding cue tones to be passed to the blind user through the upper sound holes 11, so that the light-emitting status of the light-emitting light strip 4 is controlled by the blind user conveniently. Further, the blind user can press the control button 51 corresponding to the loudspeaker 7, so that the loudspeaker 7 emits the warning sound specifically designed for blind people. The warning sound is passed to the surroundings through the side sound holes 12 to catch attention from others to ask for help or warn others.

The battery 53 is arranged in the handle 1. The battery 53 is electrically connected with the main control chip 52, the light-emitting light strip 4 and the loudspeaker 7, respectively, and is used for providing power for the light-emitting light strip 4, the loudspeaker 7 and the control module 5. The power of the battery 53 is available for the light-emitting light strip 4 to continuously emit light for more than 3 h so as to guarantee long-time outdoor activities for blind people.

In conclusion, the whole cane body of the white cane according to the present disclosure can emit light, and auditory prompts can be passed to others with a loudspeaker, so that visibility of the blind user for others is obviously improved, and then traveling safety of blind people is greatly improved. A light strip of the white cane according to the present disclosure can emit various colors of light, and the applicability is balanced during day and night, so that blind people can travel out all the day comfortably.
